In 1967, William Shatner played 34-year old Captain James T. Kirk in the Star Trek episode "The Deadly Years." A strange affliction struck members of a landing party, causing them to age rapidly. Within hours, they became elderly, infirm and partially senile.

At the time, Shatner was 36 years old. Now he's 81. Did the makeup artists accurately predict what he'd look like?

Slate has a slideshow comparing the way several actors were aged with both makeup and time, including Crispin Glover and Tom Wilson of Back to the Future and Orson Welles of Citizen Kane.
